Title: Improvements in or relating to apparatus for measuring and/or controlling temperatures
IPC: G05D23/27
Filed: 1949-07-05
Abstract: 684,156. Electric indicating systems. TINSLEY (INDUSTRIAL INSTRUMENTS), Ltd., and STEGHART, F. L. F. June 30, 1950 [July 5, 1949], No. 17688/49. Class 40 (i) [Also in Groups XXXV and XL(b)] A plurality of pyrometers disposed at various points, e.g. in a furnace, the temperature of which is to be measured or controlled, are so connected that only the pyrometer giving the maximum read-' ing is effective. The pyrometers are each connected through a D.C. amplifier (not shown) to respective load resistors R1, R2, R3, R4, the voltages developed across which are applied through respective rectifiers D1 ... D4 to charge a common condenser CO whereby the condenser is charged to a voltage dependent only on the pyrometer responsive to the maximum' temperature. A portion of this voltage is bled off by a potential divider R5, R6, R7 and fed to a mirror galvanometer G which deflects proportionally to the temperature, and varies the amount of light from a source L reflected on to a photocell PH whereby the phase of the grid energization of a gas filled triode T is varied relative to the A.C. fed anode to adjust the average anode current in accordance with the effective temperature. The temperature is indicated or controlled by an instrument connected in the anode circuit across terminal O. The sensitivity of the photocell operated amplifier T is enhanced by positive feedback through the resistor R6. According to the Provisional Specification the invention may be used to compare currents proportional to physical magnitudes such as temperature, pressure, flow or pH value, and operating apparatus under the control of that variable having the highest instantaneous value. An automatic temperature control system (see Group XXXV) is also disclosed Fig. 2 (not shown).

Title: Improvements in or relating to machines for sorting perforated record cards
Filed: 1937-06-25
Abstract: 497,756. Statistical machines. BRITISH TABULATING MACHINE CO., Ltd. June 25, 1937, No. 17785. Convention date, June 26, 1936. [Class 106 (i)] A machine for sorting perforated record cards of the type in which the cards are sorted, under the control of a reading-brush B, directly and selectively by guides 11 into channels leading to individual card boxes, has the guides arranged in intercalated groups, each group being controlled by a selecting member 12 or 13 and an electromagnet SM1 or SM2 and there being a commutator 23 to connect the magnets to the brush in succession repeatedly. The invention is described in relation to a machine of the type set out in Specification 242,654, [Class 106 (i)]. The twelve sorting blades 11 are divided into two groups, viz. the 9, 7, 5, 3, 1, 11 blades and the 8, 6, 4, 2, 0, 12 blades respectively. The first group of blades rests on the selecting member 12 which is part of the armature 14 of sorting magnet SM1, and the second group similarly coacts with selecting member 13, armature 15 and magnet SM2. Two staggered rows of conducting spots 27, 26 on commutator 23, correspond respectively to the first and second groups and coact respectively with brushes 29 and 28 and sorting magnets SM1 and SM2. The spots 27, 26 are all connected electrically to a common ring 24, in turn connected by brush 25 to the card reading brush B. This brush B is thus connected alternately and repeatedly, to the magnets SM1 and SM2, as it reads the successive hole-positions in the card column, so that when it reads a hole the appropriate magnet is energized to lower the correct member 12 or 13 to pass the card into the correct channel between the blades 11. The latter may be divided into three groups, if desired, with three selecting members and three electromagnets.

If R 1  or R 2  is in the 2- or 7-position and represents an azido group, then the compound can also be present in the isomeric tetrazole form. Starting materials. The preparation of the following compounds is given: 2 methyl-7- azido -, 4 - methyl - 2,7 - diamino -, 2 - methyl- 5 - ethoxy -, 2 - methyl - 7 - [(bis - methyl - sulphonyl) - amino] - and 2 - methyl - 7 - [# - hydroxy - ethyl) - amino] - 1,8 - naphthyridines. 2 - Methyl - 7 - hydrazino - 1,8 - naphthyridine is prepared by reacting 2-methyl-7-chloro-1,8- naphthyridine with hydrazine hydrate.
